Description

Floating Structure Mooring System

[0001] The present invention relates to a mooring system for a floating structure, and more particularly, to a mooring system for a floating structure that is capable of preventing the upper part from being exposed when the water level drops and of preventing the inhabitation of aquatic organisms.

[0002] A typical floating solar power plant mooring system uses ropes or wires that connect concrete anchors installed on the perimeter of the floating solar power plant to the floating solar power plant.

[0003] As published in Korean Patent Publication No. 10-1162473, a rope or wire extended from an anchor is installed on a floating solar power plant and a weight is installed at the end so that tension is maintained even when the floating solar power plant is raised or lowered due to changes in water level.

[0004] Meanwhile, public projects that can contribute to the expansion of fishery resources, such as installing artificial reefs, have been underway for a long time, as fish have a natural tendency to hide in the shade.

[0005] When floating solar power plants are installed in freshwater, research results show that over 90% of fish live under the shade provided by the floating solar power plants. Therefore, it is expected that the installation of floating solar power plants will contribute to the revitalization of fish resources.

[0006] However, the method of mooring floating solar power generation devices using ropes or wires has limitations in increasing the acceptance rate of local residents for installing floating solar power generation devices due to the problem that the nets or fishing lines used by fishermen for fishing become entangled in the ropes or wires, making it difficult to fish.

[0007] Therefore, to ensure that fishing and solar power generation businesses can coexist, a structure is required that allows fishing activities to take place between solar power plant arrays.

[0008] Meanwhile, in the case of marina breakwaters or mooring facilities for floating solar power plants, vertical fixed pipes are sometimes installed to respond to water level fluctuations. However, this structure has the disadvantage that when the water level drops, the upper portion of the vertical fixed pipe is exposed above the water surface, damaging the marina harbor landscape.

[0009] The present invention is intended to solve the above-mentioned problems, and provides a floating structure mooring system that enables fishing around the floating structure without using ropes or wires and does not damage the surrounding scenery even when the water level drops.

[0010] The mooring system for a floating structure of the present invention is characterized by comprising a support unit including a fixed support extending vertically upward from an anchor, and an elevating support that is connected at the top to a floating structure floating on water and is capable of being raised or lowered relative to the fixed support depending on the water level, wherein the fixed support is accommodated internally or inserted into the fixed support.

[0011] It is preferable that the floating structure mooring system of the present invention further includes a cover member arranged around the perimeter of the support unit, the upper part of which is connected to the upper part of the lift support and the lower part of which is connected to the anchor, and which is length-extensible according to the elevation of the lift support.

[0012] It is preferable that the above anchor has a fixed support member with a lower portion fixed below the water surface and has a plurality of weight blocks that are mutually stacked and penetrate the center.

[0013] It is preferable that the above-mentioned elevator support be formed such that its outer diameter corresponds to or is smaller than the inner diameter of the above-mentioned fixed support, and that the base support unit further includes an elevator guide bar extending vertically within the above-mentioned fixed support and having an outer diameter corresponding to the inner diameter of the above-mentioned elevator support.

[0014] The above fixed support is formed to have a diameter corresponding to or smaller than the inner diameter of the above-mentioned elevator support, and the base support unit may further include an elevator ring protruding along the circumference direction on the lower outer surface of the elevator support, a plurality of guide bars having lower portions fixed to the anchors around the reinforced elevator support and extending up and down to penetrate the elevator ring, and a guide ring positioned above the elevator ring and penetrating the elevator support by connecting the upper ends of a plurality of the above-mentioned guide bars spaced apart from each other in the circumferential direction.

[0015] In addition, the above-mentioned support unit may further include an elevation shock-absorbing spring that elastically supports the elevation ring lowered together with the elevation support by having the guide bar penetrate the center and being positioned below the elevation ring.

[0016] It is preferable that the floating structure mooring system of the present invention further includes a structure connecting unit connecting the frame of the floating structure and the lifting post.

[0017] The above structure connecting unit preferably comprises a structure mounting bar having one end longitudinally fixed to an edge of a frame of the above floating structure and extending vertically, a link bar having one end rotatably connected to the structure mounting bar in the vertical direction and the other end rotatably connected to an upper side of the elevator support, a movable block accommodated in the frame extending in a direction perpendicular to the link bar and having one end of the structure mounting bar coupled to a long hole extending in the longitudinal direction of the frame, and a pair of horizontal shock-absorbing members accommodated in the frame so as to be disposed on both sides of the structure mounting bar and elastically supporting the movable block in a mutually opposite direction.

[0018] The floating structure mooring system of the present invention has the advantage of enabling fishing using nets or fishing lines around the floating structure by applying a vertical and longitudinally extending support unit.

[0019] In addition, the floating structure mooring system of the present invention has the advantage of not damaging the surrounding landscape even when the water level drops, since the lifting posts are raised and lowered together with the floating structure relative to the fixed posts according to the water level.

[0020] In addition, the floating structure mooring system of the present invention is provided with a cover member around the support unit, so that attachment of attached organisms to the support unit can be fundamentally prevented.

[0021] In addition, the floating structure mooring system of the present invention has the advantage of being easy to maintain the structure to prevent attachment of attached organisms by removing the outermost cover member among a plurality of cover members when the outermost cover member is damaged by attached organisms or deteriorates due to repeated lengthening, thereby allowing the inner cover member to come into contact with water.

[0030] Hereinafter, a floating structure mooring system according to the present invention will be described in detail with reference to the attached drawings.

[0031] FIG. 1 and FIG. 2 illustrate a floating structure mooring system (10) according to a first embodiment of the present invention.

[0037] The fixed support (32) is formed in a circular shape, and a screw (34) is provided that is formed to taper downwards at the lower part inserted under the water surface and has spirally extended wings formed on the outer surface.

[0038] In addition, it is preferable that the support unit (31) further include a load transfer plate (38) that protrudes from the lower outer surface of the fixed support (32) and supports the lowest weight block (13) among the multiple weight blocks (13) so that the load of the weight block (13) can be transferred to the fixed support (32) and fixed by insertion under the water surface.

[0039] The elevator support (36) is a tubular shape having an outer diameter corresponding to or smaller than the inner diameter of the fixed support (32) to be accommodated within the fixed support (32) and having an inner space open downwards, and an air exhaust hole (37) is formed at the top to communicate with the inner space.

[0040] The structure connection unit (51) has a structure mounting bar (52) that is fixed at one end in the longitudinal direction to the edge of the frame (3) of the floating structure (1) and extends vertically, and a link bar (56) that is connected at one end to the structure mounting bar (52) so as to be able to rotate vertically relative to the structure and at the other end is connected to the upper side of the elevator support (36) so as to be able to rotate vertically relative to the structure.

[0041] The link bar (56) is rotatably connected on one side to a first pivot support piece (53) that extends from the outer surface of the structure mounting bar (52) toward the support unit (31), and is rotatably connected on the other side to a second pivot support piece (54) that protrudes from the side of the elevator support (36) so as to face the structure mounting bar (52) in parallel with the first pivot support piece (53).

[0042] The structural mounting bar (52) is mounted on the upper surface of the frame (3) so as to extend upward with respect to the frame (3), but unlike the drawing, one end may be mounted on the lower surface of the frame (3) so as to extend downward with respect to the frame (3).

[0043] The floating structure mooring system (10) according to the first embodiment of the present invention has an advantage in that it is possible to fish using a net or fishing line around the floating structure (1) by applying a vertical and longitudinally extendable support unit (31).

[0044] In addition, the floating structure mooring system (10) according to the first embodiment of the present invention has an advantage in that the surrounding landscape is not damaged even when the water level drops, since the lifting support (36) is raised and lowered together with the floating structure (1) according to the water level with respect to the fixed support (32) of the support unit (32).

[0045] Meanwhile, FIGS. 3 and 4 illustrate a floating structure mooring system according to a second embodiment of the present invention. Components having the same functions as those in the previously illustrated drawings are indicated by the same reference numerals.

[0046] A floating structure mooring system according to a second embodiment of the present invention further includes a cover member (61) that can be lengthened according to the elevation of the elevator column, in addition to the structure of the first embodiment of the present invention.

[0047] The cover member (61) is installed in a multiple-piece manner around the support unit (31), and the upper part is fixed to the edge of the support ring (63) protruding along the circumference direction on the upper outer surface of the lifting support member (36), and the lower part is fixed to the upper surface of the anchor (11) or the outer surface of the fixed support member (32) protruding upward with respect to the anchor (11).

[0048] The cover member (61) may be formed of a synthetic resin material and have a thin corrugated pipe structure, or may be formed of a vinyl material.

[0049] In addition, it is preferable that a through hole (65) be formed in the support ring (63) so that air between the cover member (61) and the support unit (31) is discharged upward when the length of the cover member (61) is reduced.

[0050] The floating structure mooring system according to the second embodiment of the present invention is provided with a cover member (61), so that attachment of organisms to the support unit (31) can be fundamentally prevented.

[0051] The floating structure mooring system according to the second embodiment of the present invention has the advantage of being easy to maintain the structure to prevent attachment of attached organisms by removing the outermost cover member (61) among a plurality of cover members (61) when the outermost cover member (61) is damaged by attached organisms or deteriorates due to repeated lengthening, thereby allowing the inner cover member (61) to come into contact with water.

[0052] Meanwhile, FIG. 5 illustrates a portion of a floating structure mooring system according to a third embodiment of the present invention. The floating structure mooring system according to the third embodiment of the present invention further includes a lifting guide bar (75) of a support unit (31) in addition to the structure of the first or second embodiment of the present invention.

[0053] The lift guide bar (75) extends up and down within the fixed support (32) and has an outer diameter corresponding to the inner diameter of the lift support (36), thereby guiding the lifting direction of the lift support (36) according to the water level.

[0054] The floating structure mooring system according to the third embodiment of the present invention is provided with a lifting guide bar (75), so that the lifting efficiency of the lifting support (36) in the vertical up-down direction can be improved.
